TUESDAY, April 20, 2021 (HealthDay News) -- If you've ever scoffed at warnings that too much red or processed meat is bad for the heart while oily fish is good for you, there's now some visual evidence to support that advice.
British researchers used heart imaging to see how these foods affected volunteers' heart health.
Brain activity increases when you start to learn a new language, but slows down as you become more proficient, a new, small study finds.
"In the first few months, you can quantitatively measure language-skill improvement by tracking brain activations," study co-author Kuniyoshi Sakai, a neuroscientist at the University of Tokyo, said in a school news release.
Patients who wear face masks with metal parts or coatings during MRIs could suffer facial burns, the U.S. Food and Drug Administration warned Monday.
That's because metal parts such as bendable nose clips or wires, staples on the headband, nanoparticles (ultrafine particles), or antimicrobial coating that may contain metal (such as silver or copper) can heat up during an MRI.
For years, people with implanted heart devices have been told they can't undergo MRI scans. But a new study adds to evidence that, with certain measures in place, the procedure is safe.
The study focused on patients with older pacemakers and implantable defibrillators that were not designed to be more compatible with MRI scanners. The researchers found that when a particular protocol ...
Adding MRI to a standard tissue biopsy appears to enhance the accuracy of a prostate cancer diagnosis, new research finds.
The study, led by researchers at the U.S. National Cancer Institute (NCI), found that combining the two methods cut the rate of "underdiagnosis" by more than half, compared to use of either MRI or biopsy alone.
Health experts already know that women with extremely dense breasts don't get the same benefit from mammography as women without very dense breast tissue. But what hasn't been clear is if MRI screening might spot cancers that mammography didn't.
Now a new study from Dutch researchers found that when MRI was used in between mammography appointments, the women in the study were half as...
Many people think of their brain as an overstuffed attic. Every square-inch is either crammed with information or working overtime to help the body function properly. So is it even conceivable that a person be normal with just half a brain?
Yes, apparently it is, according to a new analysis that assessed brain health among six adults who had undergone a hemispherectomy as child...
When a loved one shows signs of dementia, sometimes a head injury is the cause and MRI scans can help prevent a misdiagnosis of Alzheimer's, researchers report.
As many as 21% of older adults with dementia may be misdiagnosed with Alzheimer's disease, a previous study found. Up to 40% of dementias are caused by conditions other than Alzheimer's disease, according to the Alzhei...
Concussion damage may linger a full year after an athlete returns to play, Canadian researchers report.
"Brain recovery after concussion may be a more complex and longer-lasting process than we originally thought," said lead investigator Nathan Churchill, a research associate in the Neuroscience Research Program at St. Michael's Hospital in Toronto.
Despite efforts from medical groups to cut down on the overuse of CT scans and MRIs for safety reasons, their use has instead increased, a new study shows.
"Medical imaging is an important part of health care and contributes to accurate disease diagnosis and treatment, but it also can lead to patient harms such as incidental findings, overdiagnosis, anxiety and radiation exposure that...
Breast MRI screening is a good way to detect small tumors, but it's unclear how much it benefits women with a history of breast cancer, a new study finds.
Right now, experts recommend that breast cancer survivors have yearly mammograms to help catch any recurrences early. An unresolved question is whether adding breast MRI to that screening is beneficial.
If you have tattoos, it's probably safe to get an MRI scan, European researchers say.
While millions of people with tattoos have MRIs every year without side effects, some adverse reactions have been reported. Researchers said there had been no systematic studies of how safe it is for people with tattoos to have an MRI.
Reported side effects include a pulling sensation on ta...
